Cause Analysis on Buildup Formation of Carbon Sleeve in Continuous Annealing Furnace for Low-Temperature Grain-Oriented Silicon Steel Production

摘要

Based on the investigation and study of the topography and composition of the buildups, combined with production process of low-temperature grain-oriented silicon steel, the mechanism and major causes of forming buildups of carbon sleeve were discussed from the factors such as the quality of carbon sleeve, antioxi-dants, furnace atmosphere, dew point, running speed of carbon sleeve, and so forth. Meanwhile, some countermeasures to reduce the formation of the buildups were proposed.
